The festival of seven-legged racing takes place around the cathedral in Exeter on the third Thursday after the second full moon after Ash Wednesday.
The seven-legged race comprises teams of six people who race around the cathedral close in an anti-clockwise direction. The prize is won by the first team to cross the finishing line having completed 66 laps. The race was started in 1541 by boys who had been unsuccessful in their attempts to join the cathedral choir and who wanted to put a curse on the building by invoking the spirit of the Antichrist with their 6 x 66 idea.
Initially, the teams were tied together with a rope that went around people’s waists so that everyone had the use of both legs, but in 1652 the rules were changed by Cromwell, who wanted to make the race less fun and more puritanical by tying people’s legs together. Thus the tradition was born which is maintained to this day.
